The 106 Soil Units form 26 Soil Groups. The FAO soil map was a very simple classification system with units very broad, but was the first truly international system, and most soils could be accommodated on the basis of their field descriptions. The FAO soil map was intended for mapping soils at a continental scale but not at local scale.
gaez.fao.org /pages /ecocrop-find-plant Ecocrop was a database used to determine the suitability of a crop for a specified environment. [ 1 ] Developed by the Food and Agriculture Organization of the United Nations (FAO) it provided information predicting crop viability in different locations and climatic conditions. [ 2 ]
FAOSTAT serves as the foremost authoritative source of agrifood systems data, including food security, agriculture and nutrition; agriculture production and trade; prices of commodities; investment; population and employment in agrifood systems; food and diet; land, inputs and sustainability, climate change and agrifood systems emissions; structural data on agriculture; and it includes data ...
The Global Soil Partnership, [2] GSP, was initiated by the Food and Agriculture Organization (FAO) and its members with the hope to improve governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food-secure world, as well as support other essential ecosystem services.
An Alisol is a Reference Soil Group of the World Reference Base for Soil Resources (WRB). [1] Alisols have an argic horizon, which has a high cation exchange capacity. In the subsoil, the base saturation is low. There exist mixed forms, for example 'Stagnic Alisol', that are mainly Alisol, but also contain components that are found in Stagnosols.
Soil texture triangle showing the USDA classification system based on grain size Map of global soil regions from the USDA. For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.
Australia adopted this system, and its equal logarithmic intervals are an attractive feature worth maintaining. [4] The United States Department of Agriculture (USDA) adopted its own system in 1938, and the Food and Agriculture Organization (FAO) used the USDA system in the FAO-UNESCO world soil map and recommended its use.
